    Since it is cold out, are you leaning out the engine to get decent temps? You may have to richen it up and cover the head with a sock or tin foil. Hot plugs do not automatically make the engine run hotter.

    ^^^^^^^^^^

    I agree. Too lean. Start by running a body with no cut outs in the windshield and richen up the main needle by about 1/2 turn and re-tune from there.

    At least the plugs blew before the engine!

    (how cold was it when you were running?)

    3 plugs in 15 min + the same/previous problems you had with the cold plugs would lead me to believe there is an internal problem with the engine: Debris floating around inside the combustion chamber from a bad Crank bearing or broken piston skirt will kill a plug quick.
    Hopefully it is just tune related (lean), richen the tune and see if the problem persists. If it does, its time to tear it down and have a look at the internals.
    No slipper/tall gearing/power = broken parts.
